最近比较忙，没有时间更新blog了，忙里偷闲跑出来冒个泡泡贴点东西。
前段时间贴了关于s60 2nd平台创建cmwap接入点的方法，很多朋友问我如何创建
基于cmnet的接入点，其实基本上是完全一样的，所不同的是需要把proxy设置相关
的地方给去掉即可（我们都是中国移动的“好孩子”）。

使用的时候只需要在CSocketEngine::ConstructL()中加入这个即可。
void CSocketsEngine::ConstructL(TInt down_type) {ChangeStatus(ENotConnected);
// Start a timeriTimer = CTimeOutTimer::NewL(EPriorityHigh, *this);CActiveScheduler::Add(this);
// Open channel to Socket Serverif(down_type == HTTP_DOWN_CMNET) ConnectSmoothCMNET() ; else ConnectSmoothCMWAP() ;
// Create socket read and write active objectsiSocketsReader = CSocketsReader::NewL(*this, iSocket);iSocketsWriter = CSocketsWriter::NewL(*this, iSocket); }
这些都是在6670真机上测试过的代码，应该不会有问题。
希望可以帮助到对此还有困扰的朋友，这个是断点续传的测试安装包，有兴趣的朋友可以
实验一下：
